DY'EING-MAGHINE.

Application filed December 22, 1916.

To all whom it may concern Be it known that I, lilowann M. DUDLEY, acitizen of the United States, and a resident of Philadelphia, in thecounty of Philadelphia and State of Pennsylvania, have invented certainnew and useful Improvements in Dyeing-lllachines, 01 which the :lollowing is a specification.

My invention relates to a dyeing machine and refers particularly to amachine adapted for the dyeing of textile fibers compressed within adyeing chamber, the dye ing being accomplished by the forced passage oi?the dye liquor through the liber mass.

Among the objects of my invention is a dyeing machine particularlysuitable for the dyeing of warps in the ball, whereby the condition ofthe fiber may be accurately and readily judged at any stage oi the treatment without opening the dyeing chamber and whereby even results may beobtained without disturbing the fiber to be dyed.

Other objects of my invention will be evident upon a consideration of myspecification and claims.

I have found that the even or uneven dye-- lug results obtained in amachine of this general character depends largely upon the particularshape of the openings through which the dye liquor enters the libermass, and that unevenness can be prevented by the use of openings of aparticular shape, the conformation of which enables the liquor to spreaditself through the fiber mass without the formation or channels of How.

l have further found that this desirable result can be obtained if suchopenings are of a pyramidal iorm, diverging upwardly into the dyeingchamber or of a double diverging conformation, diverging both upwardlyinto the dyeing chamber and downwardly into the source of dye liquor,and further, that the evenness of the dyeing may be further enhanced bycausing the dye liquor to pass through a chamber conta1ning pyramidal.shaped tubes before passing into the dyeing chamber.

Related forms of my device are shown in the accompanying drawings, inwhich similar parts are designated by s1milar numorals.

invention, partly broken away to disclose a portion in cross-section.

Fig. 2 is a cross-section through the line 22 oi. Fig. 1.

Fig. Ilis an enlarged cross-section of the pyramidal tubes introducedinto the liquor supply chamber.

Fig. at is a top plan view of the pyramidal tubes.

Fig. 5 is a broken side view of one modification ojl' my device showingan upper and a lower arrangement 01" the pyramidal tubes in the liquorsupply chamber.

Fig. 6 is a cross-section of the pump chambcr showing the py amidaltubes extending downwardly therein.

'l. he outer portion of the dyeing machine comprises the rectangularshell r and the rectangular shell 8, fixedly attached to each other bythe bolts 9, 9; the pyramidal shaped shell 10 fixedly attached to theshell 8 by the bolts 11 11 and the centrifugal pump 12 fixedly attachedto the shell 10 by the bolts 13, 13. A 'loraminous plate 1a is situatedbetween the shells 7 and 8 integral with the walls of the shell 8. Theloraminous plate 14lcarrics pyramidal shaped openings 16, 16 divergingboth upwardly and downwardly from their centers.

The machine is provided with a removable annular :toraminous plate 17,the construction of which is similar to the foraminous plate 1%.

An annular angle-shaped member 18, is slidable within the shell 7,capable of abutment upon the plate 17 and maintained in any desiredposition by means of the thumb screws 19, 19, which thread within theshoulders 20, 2O fixedly attached to the shell 7.

A series of pyramidal tubes 21, 21 are positioned in the interiorportion ol the shell .10, extending from the top to the bottom thereof,their upper ends il, ll and lower ends L2, 42 being flared or diverged.

In the ll'lOCllllCt tion shown in Fig. 5, the ayramidal tubes 21, 21 arereplaced by pyramidal tubes 92, 22 extending downwardly from the top ofthe chamber within the shell 10, and pyramidal tubes 23, 23 eX- tendingupwardly from the bottom of the chamber within the shell 10, the twoseries of pyramidal tubes being in alinement with each other.

In the modification shown in Fig. 6 the liquor is forced upwardlythrough the py inthe sample device 37. started and the valve 33 opened,allowing "the liquor to flow through thefp'ipe -32into pyramidal tubes23, 23 are replaced by pyramidal tubes 24L, 2 l- Whi'ch extend down-Wardly beyond the lower portion of the chamber Within the shell 10 intothe chamber of the rotary pump 12.

A perforated steam pipe 25 is introduced into the chamber formed by theshell 8.

In order to facilitate reference to the yarious chambers, they willhereafter be referred to as the top chamber 2 6, the dyeing chamber 27,the liquor supply chamber 28, the tube chamber 29, and the pump chamber30.

iin over-flow pipe 31 connects the top chamber 26 with the centrifugalpump 12 toallow ofcontinuous flow of the liquor upwardly through themachine- A pipe 32 connects the pump 12, with a liquor supply tanl'ciiotshown, the-pipe 32 carrying the alve y A pipe "34-, 35 extends ii-omWithin the liquorsupp'ly chamber 28to a pointabove the-top chamber 26,and carries a-therinometer 36 for registeringthetemperature passing 2through the pipe 34, '35.

Asample'tlyeingmachine 37, exactly similar to the above describeddyeingmachine, except in smallerproportions, is connected totheliquorsupply chamber 28 by the pipe 38 :and'to'the top chamber 26 bythe pipe ii i I i I '89. The sample material- 1n themachine 37 is eiraininedbyremovingthe top to which IStllI'QEtClQCl tothe sample machine 37.

The operation of the device; is as follows Th'e annular member 18 andthetoramiupon'thegoo'ds by means ofthemember-18. Asmall quantity of thesame goods 1s placed The pump *12 is the pump 12, by which it is forced"up- Warclly through "the pump chamber 30, the tube chamber 29, theliquor supply chamber '28, and thegoo'ds' in'the dyeing chamber 27,

' into 1 the top member 26. When the liquor has reached a height "to"allow its flow through the pipe "31 back-into-thezpump12,

'thevalve 33 closed and the liquor is forced 'continu'ou sly through thedevice as above stated.

From time to time, the valvebl is closed, thetop 401s removed forthepurposecf examining the condition of the dyeing 0peration, and isthen replaced, the valve 51 opened; and the dyeing continued until ithas reached a satisfactorycondition.

It is evident that during this operation the ramidal tubes 21, 21,theupper endsof'which cause it to spread out upon leaving the tubes, theflow of the liquor thus eirerting an upiyardly divergent force. As theliquor leaves the spaces in the foraminous plate 16, the divergent edgesof the separating members cause it to spread out and to impinge upon thematerial. in the dyeing chamber 27 in a "practically uniform manner, andthat the continuing of this flow Will force the liquor throughout themass oi goods, and Will prevent the formation of channels through thegoods. As the plate 17 is the same as plate l'GQthe pressure will bemaintained in the dyeing chamber 27, and the liquor Will be compelled topenetrate the goods inwardly toW'artleach off the openings in order toescape.

I do finot limit myself to the size, shape, nuniberor arrangement ofparts as shown and described, all of which may be -varied Without goingbeyond-the scope of my invention as described antl 'claimed.
